In the accompanymg drawmgs illustratmg my invention, Figure 1 isa'topplan view of.

my terminal puller applied to the'terminal of a storage battery. Figure2 is a side view of the same. Figure 3 is an end view thereof. Figure 4is a sectional viewtaken through the terminal puller itself on the line44 of Figure 1. And Figure 5 is a sectional."

view taken through the puller on the" line h 5 of Figure 2. I v sReferring to the accompanyingdrawingsfor a detailed description of myinvention, the numeral 1 designates a screw holding member that ispreferably a casting which is formed with a screw hole in its reinforcedcentral portion. 1 At one end the casting 1 is channeled as shown-inFigure 5to provide ledges 2, 2 over which the hook ends, 3, 3 of eyeletsor arms 4, ures 3 and g y The eyelets 4, 4 are put under an inwardtension by the following means. Formed in the upper end of each eyeletis a holethrough which a screw 5 is freely inserted for entrance into athreaded hole in the side of the channeled portion of the memberl.Surrounding each. screw 5 between its head andthe member 4 is a coilspring 6 that exerts an inward pressure upon its respective eyelet for apurpose to be hereinafter described.

Inserted in the screw hole in the thickened central portion of thecasting 1 is a screw or stud 7 formed with an outer wrench receivinghead 8; On its inner end thescrew 7 carries a swivel cap 9 to engagea'battery post 10 of a storage battery 10. This cap19, which does notturn when it is pressed againstan object, will prevent the screw 7 fromboring} from the latter,

The device is'ext'remely flexible and is easy 4 respectively fit (SeeFiginto the post when rotated to Formed in; the rear end .ed end of'aswivel hook 11. On the hook end of the inemberllis a hole which freelyreceives the upper threadpull aterminal of the latter there isformed atooth 12 which is adapted tofir nly engage a round cable-receiving end13, of a storage battery terminal '14 applied'to the post 10. Applied tothe upper threaded end of the swivel hook 11 is a knurled cap nut 15. iI

My improved pulling device may be applied'in the following manner toanybattery terminal, such as the terminal 14, that has i corroded onthe. postlO.

The terminal 14 carries the conventional clamping bolt 16 and nut 17.Over the head of the bolt and the nut the eyelets 4, 4 are fitted byfirst springing oneeyelet 4 over thethreaded end of the bolt and theother eyelet over the head end of the bolt. These eyelet-s or arms are:free to be'moved in any direction against the tension of the springs 6,to permit them storage battery terminal. When the screw 7 is turned'toremove the terminal from the v to be easily; applied to the bolt ends ofany any angle, is now ready to be turned to force its swivel cap 9against the post 10. lVhen the screw 7 is so turned by a wrench appliedto its head 8, it will easily lift the terminal,

14, engaged by the eyelets 4' and hookll, from the post 10.The'liftingoperation is thus performed without injury to the terminal,the post or thexbattery. Whena bar or other heavy instrument isused forthis purpose,

the battery is often severely-marred.

It will be observed that the pulling arms or eyelets 4 are at an angleof about thirteen c egrees. Therefore, the'holesin them will be the sameangle, thus forming a tooth-or claw of the lower part of the hole. Theseteeth or claws increasetheir grip as pressure from the screw 7 isapplied. 7

When the pulling operation has been acsecured t'othe other end of saidscrew holding inem'berfor engagement with the other end of saidterminal, said eyelets and hook adapted to pull the terminal from saidpost when the pressure 01' the screw is applied to the latter.

2". A device ofthe type described for pulling a terminal from a storagevbattery post, comprising a screw receiving member formed with a centralscrew hole a screw in said hole adapted to engage said post, meanssecured to the rear end of the screw member for engaging the terminal,apair of hook eyelets suspended from the front end of said memher, andtension means for forcing said eyelets toward each other for the purposespecitied.

3. A device of the type described forpulling a terminal from a storagebattery post, comprising a screw-receiving member formed with a centralscrew hole, ascrew in said hole for engagement with said post, means onthe rear end of the screw member for engaging one part or said terminal,a pair of hook eyelets suspended from the front end of the screw membereach eyelet formed with a hole in its upper portion, a screw projectingthrough said hole in each eyelet into the screw member, and a springsnrrounding each screw between its head and the screw member for thepurpose specified. r In witness whereof I have hereunto set my hand this24 day of March, 1928. 1 r
